Under certain conditions the interaction between a “polar” molecule such as HCl located at the origin and an ion located

along the x axis can be described by a potential energy U = −b/x2, where b is a constant. What is Fx, the x component of

the force on the ion? What is Fy, the y component of the force on the ion?
